SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 580,330, dated April 6, 1897. Application iiled September 14,1896. Serial No. 605,802. (No model.)

To LZZ whom t may concern,.-

Be it known that I, HERMAN RUSSELL, a citizen of the United States, residing at Den ver, in the county of Arapahoe andState of Colorado, have invented a new and useful I lnprovement in Sash-Locks, of which the following is a specification.

lMy invention relates to improvements in window-sash fasteners and supports; and it consists of the novel features hereinafter described and claimed.

My invention will be understood by reference to the accompanying drawings, wherein the same parts are indicated by the same let* ters throughout the several views.

Figure l represents a partial view of a window frame and sash, showing my sash fastener and support as it appears when in use. Fig. 2 is a section taken on the line i. 2 in Fig. 1 and looking in the direction indicated by the arrows. Fig. 3 is an enlarged detail front elevation of the sash fastener and support, the inner dotted lines indicating the spring; and Fig. 4 is a vertical section through the casing shown in Fig 3, taken on the line 4 4 in the said ligure and looking in the direction of the arrows,the spring and door being shown in dotted lines in the open position of the latter.

A represents a metal box or casing having a plate or door B hinged thereon at one end, either at the t-op or bottom, but preferably `at the bottom, by means of a bolt b', as shown in Figs.V 3 and 4. This hinged plate or door B has rigidly mounted thereon to one side a projecting lug or latch B. A spring C is mounted within the boX or casing A and tends to hold the hinged plate or door B shut, as shown in full lines in Fig. 4. This spring may be of any suitable shape, and maybe either a iiat spring, as shown in the drawings hereto annexed, or a coil-spring, but the flat spring is preferred, as being simpler and less expensive. This springis secured at one end, as at c in Fig. 4, by means of screws c or other suitable means to the back wall of the box or Casing A.

The swinging end of the hinged plate or door B is beveled or hollowed out at the outer edge, as shown at h in Fig. 4, to strike against a projecting portion a of the casing A, which forms a stop to prevent the said end of the door from swinging outward too far. This stop may be of any other suitable construction, and in place of the projection a a crossrod or bolt or other equivalent construction may be used, if preferred.

D represents a toothed or corrugated metal bar which is secured to the window-frame X by means of screws dx, as seen most clearly in Fig. 2. Thistoothed or corrugated barD is attached to the window-frame X before the strip Y is put on, and this strip Y when in position almost completely conceals the metal bar D, as seen in Fig. 2. In Fig. 4 a portion of this bar D is indicated in dotted lines.

The box or casing A is fitted into a recess or opening A0 in the window-sash Z, and the lug or catch Bon the hinged door B comes immediately behind the toothed face of the bar D and is adapted to engage between the teeth d' on said bar, as seen in Fig. 4.

The casing A may be secured to t-he sash' Z by means of screws through the rear wall thereof or by means of screws passing through the flanges a2, a3, and CL4 around said casing.

lVhen in its normal position, the hinged door or plate B will be flush withl the front of the casing A, and when it is desired to release the catch for the purposes of raising or lowering the window-sash the hin ged plate or door may be pushed inward with the thumb or finger, and the catch B', swinging inward, will become released, and the sash may be raised or lowered, as desired.

By doing away with the necessity for any knob or handle for operating the catch and by having the bar D concealed, as above described, it will be seen that a very strong and efficient sash support and fastener is pro` duced and one that will not have the objection of unsightliness, such as many fasteners of a similar nature now in use.

The many advantages of my construction will readily suggest themselves to anyone and need not be dwelt upon.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

ln a window-sash fastener and support, the combination with a metallic bar secured to the inside of the frame of the window, provided with openings in one face thereof opposite the inner side of the sash, and covered IOO spring mounted in said easing and pressing said plate outward; and a stop on said easing limiting the outward swing of said plate, substantially as described.

In testimony whereof I aiiix my signature in presence 0f two Witnesses.

HERMAN RUSSELL'.
